Technical Due Diligence Advisory Services 2026-2029

Great British Energy is seeking technical due diligence advisors to support investment evaluation over three years. Three suppliers have been awarded contracts (WSP, Buro Happold, and AtkinsRealis) to deliver technical due diligence services, alongside commercial, financial, and management assessments for projects under consideration for investment, funding, or partnership. The tiered contract structure manages potential conflicts of interest and resource constraints. The total programme value is £10m ex VAT, with each supplier eligible for up to £10m but sharing the available budget proportionally based on service delivery requirements. This opportunity was procured through the Department for Energy Security and Net Zero's Energy and Net Zero Professional Services Framework (ENZPS Framework), covering Lot 2, SD1 Policy and Strategy, and SD3 Energy Design and Delivery.
